lolzzzz before MQM was formed, there were no killings. Karachi was safer than lahore and islamabad. What are you on bro? MQM basically wanted to take control of all major areas so they can make money off ransom, protection money, water tank sale etc.
Scum like you are worse than hitmen, take your propoganda elsewhere. If there was peace then why did MQM even get all the support? BS, without MQM, whatever it may be, there is no Karachi. PPP and ANP free to plunder and loot, I can't even imagine.
The reason MQM was formed BECAUSE of the killings, it's purpose was to safeguard the property and life of urdu-speakers; the most educated, civilized, productive and rightful residents of Karachi.
